Yeah… “WHY?”
If its in a busy street, somebody may:
a) smack his/her face right into it and sue you;
b) grab and steal it;
c) use it as a target practice;
d) pose with you and steal your wallet; or
e) kill you.
Since you can’t move fast since you’re holding something heavy and fragile with your two hands, you became an easy target for other people.
